Sonic Sensation highlights
- Scream Chamber: Visitors step into a semi-soundproof chamber, close the door, and let out a scream! A partner reads the decibel meter mounted on the outside of the chamber. Compare that to other sounds on a chart. Can a visitor scream as loud as a howler monkey? The competition gets fierce and funny!
- See Sound: Watch foam bits “dance” in all kinds of interesting patterns in a long, clear tube. Speakers at both ends of the tube drive the air rapidly back and forth; although the air is invisible, it’s making the foam bits move in unexpected patterns. Below the tube is an oscilloscope illustrating the motion of the vibrating cones on the speakers. What happens to the pattern as the amplitude or frequency knobs for the speakers are turned?
- Music in Motion: Be a musician! Wiggle, jiggle, kick or flick across a musical-themed carpet while a camera overhead displays the maestro of this giant “keyboard” on a large-screen TV. Visitors move through the motion-sensing zones shown on the monitor to “play” different sounds. Explore what makes music.
- Critters in a Cupboard: A visitor hides a “cat” or “cricket” in one of the 24 kitchen cupboards and asks a partner to find it by listening! For a challenge, can they find the critters while covering one ear? A graphic explains how two ears are used to locate sounds.
- How’s your Hearing? With headphones on, visitors adjust the volume of different frequency ranges for each ear and record their results on a chart. Are the results the same for both ears? Can one ear hear certain frequencies at lower or higher volumes than the other ear?
